Specification

The 5-Mercapto-1H-tetrazole-1-acetic acid , with the CAS regiser number 57658-36-3, has the systematic name of (5-thioxo-2,5-dihydro-1H-tetrazol-1-yl)acetic acid . Besides, it could also be known to us as
mtaa ; 5-mercaptotetrazole-1-acetic acid ; 5-mercaptotetrazolylacetic acid sodium salt ; 5-mercapto-1h-tetrazole-1-acetic acid ; 2,5-dihydro-5-thioxo-1h-tetrazol-1-acetic acid ; mtaa: 5- mercapto-1h- tetrazole –1-acetic acid ; 1-carboxymethyl-5-mercapto-1,2,3,4-tetrazole ; (5-mercapto-1h-tetrazol-1-yl)acetic acid .

Characteristics of this kind of chemcial are as below: (1)#H bond acceptors: 6 ; (2)#H bond donors: 2 ; (3)#Freely Rotating Bonds: 2 ; (4)Polar Surface Area: 89.59 ; (5)Index of Refraction: 1.852 ; (6)Molar Refractivity: 35.96 cm³ ; (7)Molar Volume: 80.3 cm³ ; (8)Polarizability: 14.25 ×10^-24 cm³ ; (9)Surface Tension: 92 dyne/cm ; (10)Density: 1.99 g/cm³ ; (11)Flash Point: 126 °C ; (12)Enthalpy of Vaporization: 57.62 kJ/mol ; (13)Boiling Point: 284.7 °C at 760 mmHg ; (14)Vapour Pressure: 0.000761 mmHg at 25°C .

Being a kind of harmful chemical, it may cause damage to health. If by inhalation or swallowed or in contact with skin, it will be very harmful and it has possible risk of harm to the unborn child. So while using this kind of chemical, we should be more cautious. Wear suitable protective clothing and gloves and do not breathe dust while using. It belongs to the category of organic acids. And it is widely used in pharmaceutics, such as being the side chain of ceforanide.

As for its using in the lab, it could be used to make other substance, and you could operate in the laborary with the following steps: Firstly, prepare the reactant of (5-thioxo-4,5-dihydro-tetrazol-1-yl)-acetic acid and sodium 7-(2-thienylacetamido)-2b-methyl-3-acetoxymethylceph-3-em-4-carboxylate , and then react in the reagent of NaHCO3, phosphate buffer and solvent of H2O, for about 6 hours under the temperature of 50 ℃. Through this way, you could get the disodium 7-(2-thienylacetamido)-2b-methyl-3-(1-carborxymethyl-1H-tetrazol-5-yl)thiomethylceph-3-em-4-carboxylate .

In addition, you could convert the following data information into the molecular structure:
SMILES:O=C(O)CN1C(=S)/N=N\N1
InChI:InChI=1/C3H4N4O2S/c8-2(9)1-7-3(10)4-5-6-7/h1H2,(H,8,9)(H,4,6,10
