The molecular formula of cyclophosphamide is C7H15Cl2N2O2P•H2O and the molecular weight is 279.1. The chemical name for cyclophosphamide is 2-[bis(2-chloroethyl)amino] tetrahydro 2H- 1, 3, 2-oxazaphosphorine 2-oxide monohydrate and the following structural composition

Composition
Each vial contains Cyclophosphamide BP 200 mg & 1 gm lyophilized powder for injection.

Mechanism of action
Cyclophosphamide is first converted by the liver into two active metabolites, acrolein and phosphoramide. Phosphoramide mustard forms DNA crosslink between (interstrand crosslinkages) and within (intrastrand crosslinkages) DNA strands at guanine N-7 positions. This is irreversible and leads to cell death.
