Cetrorelix acetate is a synthetic decapeptide mainly used in assisted reproductive technology. It plays a critical role in preventing premature ovulation in patients undergoing controlled ovarian stimulation.
As a gonadotropin-releasing hormone (GnRH) antagonist, it competes with endogenous LHRH/GnRH for pituitary membrane receptors. This dose-dependent inhibition suppresses LH and FSH secretion, effectively delaying the LH peak without an initial spike in progesterone receptor activity.
TOC and conductivity of main supply and return points are monitored periodically. TOC is tested weekly by Quality Control (QC). Conductivity is monitored online and recorded every four hours by purified water station operators at primary RO, secondary RO, EDI, and distribution system total return points.
Purified Water Specification: Maintained at no more than 1.3 µs/cm at 25°C (USP standard).
Full testing is performed weekly for main supply and return points, and monthly for circulation loop user points. Full testing parameters include: characters, pH, nitrate, nitrite, ammonia, conductivity, TOC, non-volatile substances, heavy metals, microbial limits, and bacterial endotoxin.
