Cefalexin
Cefalexin (CAS: 15686-71-2; Formula: C16H17N3O4S; MW: 347.39) is an antibacterial agent belonging to the cephalosporin class. It functions by interfering with bacterial cell wall synthesis. This compound is widely used in veterinary medicine and as an analytical standard for quality control and research purposes, particularly in chromatography and biochemical applications. Tech Serve Solutions supplies Cefalexin in a VETRANAL™ analytical standard grade.
- IUPAC
- 7-(D-α-amino-phenylacetamido)-3-methyl-3-cepheme-4-carboxylic acid
Antibacterial Agent
Cefalexin is a cephalosporin antibiotic effective against a range of Gram-positive and some Gram-negative bacteria. It acts by inhibiting the synthesis of peptidoglycan, a crucial component of bacterial cell walls, leading to cell lysis and death.
Analytical Standard
As a VETRANAL™ analytical standard, Cefalexin is utilised in laboratories for calibration, method validation, and quality control in analytical techniques such as chromatography. Its well-defined purity makes it suitable for research and reference applications.
Veterinary Medicine
Cefalexin is frequently prescribed in veterinary practice to treat various bacterial infections in animals, including skin, bone, and urinary tract infections. Its broad spectrum of activity makes it a versatile therapeutic option.
