CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Solid |
|---|---|
| Color/Form | Needles from aqueous acetone |
| Melting Point | 198-200 °C (decomposes) |
| Solubility | Mol wt 476.50. White to yellowish-white, odorless crystalline powder with a bitter, salty taste. Crystallizes in alpha, beta, and gamma forms (Kariyone). Easily sol in water, slightly sol in methanol, ethanol. Practically insol in benzene, acetone, chloroform /Sodium salt/ |
| LogP | -0.58 |
| Stability/Shelf Life | Following reconstitution with sterile water for injection, bacteriostatic water for injection, or 0.9% sodium chloride injection, soln containing approx 225 or 330 mg of cefazolin per ml have a pH of approx 4.5-6 and are stable for 24 hr @ room temp or 96 hr @ 5 °C. Rapid hydrolysis of the drug occurs when pH exceeds 8.5, and precipitation of the insoluble free acid may occur when pH is below 4.5. |

PRODUCT INTRODUCTION
description
Cefazolin is a first-generation cephalosporin compound having [(5-methyl-1,3,4-thiadiazol-2-yl)sulfanyl]methyl and (1H-tetrazol-1-ylacetyl)amino side-groups at positions 3 and 7 respectively. It has a role as an antibacterial drug. It is a cephalosporin, a member of thiadiazoles, a member of tetrazoles and a beta-lactam antibiotic allergen. It is a conjugate acid of a cefazolin(1-).
