CAS Number: 68-41-7
Molecular Formula: C3H6N2O2
Molecular Weight: 102.09
Cycloserine
Cycloserine or D- Cycloserine or 4-amino-3-isoxazolidinone is an antibiotic used to treat tuberculosis or TB. Cycloserine is restricted for use only against multiple drug-resistant and extensively drug-resistant strains of TB. Cycloserine can also be used to treat urinary (bladder) tract infections.
Cycloserine USP Grade Specifications:
C3H6N2O2 --- 102.09
3-Isoxazolidinone, 4-amino-, (R)-.
(+)-4-Amino-3-isoxazolidinone CAS 68-41-7
UNII: 95IK5KI84Z
Cycloserine has a potency of not less than 900 µg of C3H6N2O2 per mg.
Packaging and storage: Preserve in tight containers.
Identification: Dissolve about 1 mg in 10 mL of 0.1 N sodium hydroxide. To 1 mL of the resulting solution add 3 mL of 1 N acetic acid and 1 mL of a mixture, prepared 1 hour before use, of equal parts of sodium nitroprusside solution (1 in 25) and 4 N sodium hydroxide: a blue color gradually develops.
Condensation products: Its absorptivity at 285 nm, determined in a 0.1 N sodium hydroxide solution containing 0.40 mg per mL is not more than 0.80.
Specific rotation: between 108° and 114°.
Test solution: 50 mg per mL, in 2 N sodium hydroxide.
Crystallinity: meets the requirements.
pH: between 5.5 and 6.5, in a solution (1 in 10).
Loss on drying: Dry about 100 mg in a capillary-stoppered bottle in vacuum at 60° for 3 hours: it loses not more than 1.0% of its weight.
Residue on ignition: not more than 0.5%, the charred residue being moistened with 2 mL of nitric acid and 5 drops of sulfuric acid.
Assay: To pass the test by chromatography.
