Photo Forum / Film Photography / Darkroom / May 2004glycin supplier and price
apr704 from Lloyd Erlick, I came across a chemical supplier website (url below) - and they list glycin under its chemical name and CAS number-- note the availablitiy of a lower grade for lower price ... [I notice that a recent thead in this ng discussing glycin contained a posting that the following is the correct formula for glycin: N-(4-hydroxyphenyl)-glycine, CAS 122-87-2. I don't know if this is the same substance, but the numbner is the same.] http://www.pfaltzandbauer.com/cgi-bin/details.pl?type=cas&order=&chem=122-87-2&p age=1&item=H16660 [start] N-(p-Hydroxyphenyl)glycine Item No: H16660 Chemical Formula: HOC6H4NHCH2COOH CAS #: 122-87-2 Melt Point: 245-247°C Molecular Weight: 167 TSCA: Listed Hazard Information: Harmless Availability: Normally a Stock Item.

Pyro goes for the equivalent of US $35.00 for 25 grams. Imagine how many users of Pyro there are here when a half liter of the stock 'A' solution would cost you almost $50.00 to make!!! I order what I can from the Formulary and what they can't ship, I try ArtCraft (they'll ship Pyro and hydroquinone). Tis a crazy world in which we live... Maybe Canada is less stringent re shipping. I believe Johnny will also ship almost anything http://www.colba.net/~fotochem/index.htm Jorge > I order what I can from the Formulary and what they can't ship, I try > ArtCraft (they'll ship Pyro and hydroquinone).

Jim you don't have to by pyro from the most expensive source, there are good alternatives if you are in germany (with the sole exception of glycin where the formulary seems to be last who make and offer it in affordable photo-grade): http://www.genec.de/pch1-2004br.htm Pyrogallol, ultra pure, 25g, EUR 14,29 http://www.omikron-online.de/cyberchem/preise/prs-html/016pl-py.htm Pyrogallol pure, 100g EUR 39,80 > I order what I can from the Formulary and what they can't ship, I try > ArtCraft (they'll ship Pyro and hydroquinone). Both are probably cheaper when ordered locally. The above sources also ship hydroquinone for reasonable prices. best Stefan > Price: $97.00 / 25 G > Price: $219.00 / 100 G Photoformulary sells Photoglycin (N-(parahydroxy- phenyl) glycine) for USD 71 per lb, 100g for USD 16,50. http://www.photoformulary.com/DesktopDefault.aspx?tabindex=2&tabid=9&CategoryID= 23&langID=0 best Stefan Bryant Labs sells 500 grams of glycin for $66. http://www.bryantlaboratory.com/ChemicalListG-HPhoto.htm > Bryant Labs sells 500 grams of glycin for $66. > http://www.bryantlaboratory.com/ChemicalListG-HPhoto.htm Rayco in the UK sell it. From their website: GLYCIN (g) 38.06 60.91 Prices are in UK pounds, ($1 was 0.58 pounds when I got some to take with me to the USA last week) the first price is for 5g, the second for 25g. I don't know why it is so expensive. >glycin for $66 may104 from Lloyd Erlick, their page shows the following: Glycine, Reagent, A.C.S. 100g G325Q2 $17.60 500g G325W2 $66.00 We get back into the old glycine vs glycin muddle. There is also the glycin packaged for use in the fur dressing and dying industry. I have tried it on prints and it is not pretty. Who will step up to the plate and spring for the 100 grams to test it out? I, for one, will send two bucks to support the cause ... regards, --le > We get back into the old glycine Vs glycin muddle. There are two glycin(e)s: one a simple amino acid, cheap and common as snot (buy a bag of corn...); the other is 'photographic', having a ring structure with all sorts of hangers on attached to the amino acid glycin(e). Either can be spelled with or without the final 'e'. In the US the 'glycine' usually (but not always) indicates the amino acid and 'glycin' the developing agent. In TROTW (like, not in the US) both forms are spelled 'glycin' (sometimes) with the developing agent identified as 'photographic glycin(e)'. If it is cheap it is probably the wrong glycin(e). The Bryant labs stuff is listed under photographic chemicals, so one has to assume it is the developing agent. If it turns out to be corn extract there would be excellent grounds for returning the stuff. I don't understand selling 'reagent grade' for photography. Photo grade is usually somewhere between 'technical' and 'floor sweepings', often a fraction of the cost of reagent grade.  SignatureNicholas O.

Remove spaces etc. to reply: n o lindan at net com dot com I think the safest way would be to email (they do have one?) the seller and ask.
