EthinylestradiolChlormadinoneQualityChecker

1. Scope

The Ethinylestradiol Chlormadinone Quality Checker utility is used for Ethinylestradiol Chlormadinone. The actual input.csv is the source of truth for the input structure; control criteria are defined by the executable and the domain description.

The utility does not use machine learning; decisions are produced by deterministic rules.

Categories: Contraceptives

Tags: assay, biologics, contraceptives, dissolution, fixed-dose combinations, heavy metals, hormones, impurities, microbiology, radiopharma, residual solvents, solid dosage

2. Execution modes

EthinylestradiolChlormadinoneQualityChecker.exe                            → demo mode (console output)
EthinylestradiolChlormadinoneQualityChecker.exe input.csv output.json      → evaluate your data

3. Key controlled areas

• assay / content
• purity and impurities
• dissolution / disintegration
• residual solvents
• microbiology and pathogens
• heavy metals / elemental impurities
• pH and physicochemical parameters

5. URS — user requirements

6. input.csv data contract

The source of truth for the input schema is the actual input.csv header. Column names are technical identifiers and are not translated.

7. FS — functional specification

8. output.json contract

The output file must be suitable for automated processing, audit review and correlation with the source input.csv row.

9. OQ/PQ test scenarios

10. QA/QC, CSV and change control

• Before production use, the client records executable version, checksum, specification/monograph version, test CSV, expected JSON and IQ/OQ results.
• Column names must not be changed without updating the validator and test scenarios.
• The source CSV, output.json and utility version should be stored together as an evidence package.
• Any change in control rules must go through change control and repeated OQ scenario verification.
