14110-97-5 Usage
Chemical Properties
Off-White Powder
Uses
A useful sulfhydryl reagent, 4-(ChloroMercuri)benzenesulfonic Acid SodiuM Salt reacts with Histidine 225C, a residue of the NhaA-Na/H Antiporter of Escherichia Coli. More soluble than p-chloromercuribenzoic acid
Purification Methods
The free acid is obtained by acidifying an aqueous solution, filtering off the acid, washing it with H2O and recrystallising from hot H2O to give a colourless solid which is dried in a vacuum over P2O5 and should be free of Cl-ions (AgNO3 test). The Na salt is made by dissolving it in one equivalent of aqueous NaOH and evaporating to dryness. [Nesmejanow et al. Chem Ber 67 130 1934, Boyer J Am Chem Soc 76 4331 1954.] HIGHLY TOXIC.
Check Digit Verification of cas no
The CAS Registry Mumber 14110-97-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,1,1 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14110-97:
(7*1)+(6*4)+(5*1)+(4*1)+(3*0)+(2*9)+(1*7)=65
65 % 10 = 5
So 14110-97-5 is a valid CAS Registry Number.
