Could someone get the formulas on these document please it would really help out us students using the site for research

---I changed some of the information, which I found out wrong (source : Merck Index 13th edition). I don't know about the rest of the article.

I think that under the label "Buffering Features" talks too much about EDTA.

Infobox

If anyone ever wants to construct an infobox, here are the particulars. savidan^{(talk) (e@)} 09:02, 9 April 2006 (UTC)[reply]

(1) CAS No: 77-86-1; MF: (HOCH2)3CNH2; MW: 121.13624; BP(°C): 219-220(p=10 torr)

(2) Specification of Tris:

Appearance: white crystal

Content: ≥99.9%

Melting point: 168-171℃

Loss on drying: ≤0.5%

ASH: ≤0.05%

PH (0.1mol/L, 25℃):10.0-10.8

Insoluble in water: ≤0.03%

ABS (260nm): ≤0.2

Heavy metals: ≤5PPM

Fe: ≤5PPM

SO42+: ≤5PPM

Cl: ≤5PPM

Some of the analysis information you have here is only going to be specific to that lot. They aren't innate properties of tris itself. Benzene 15:10, 6 June 2006 (UTC)[reply]

Systematic name

The two alternative systematic names: 2-amino-2-hydroxymethyl-1,3-propanediol or 2-nitro-2-hydroxymethyl-1,3-propanediol describe quite different compounds. I would suggest that the latter (2-nitro) be deleted. Dr Thermo 15:23, 26 October 2007 (UTC)[reply]
