Simazine is 1,3,5-triazine herbicide, absorbed mainly through roots. Systemic and selective in nature, it binds to the Q_B site on the D1 protein of the photosystem II complex, disrupting photosynthetic electron transport. Simazine is used for pre-emergence control of annual grass and broad-leaved weeds in pome fruit, stone fruit, bush and cane fruit, citrus, vines, strawberries, nuts, olives, pineapples, field beans, French beans, peas, maize, sweet corn, asparagus, hops, alfalfa, lupins, oilseed rape, artichokes, sugar cane, cocoa, coffee, rubber, oil palms, tea, turf, and ornamentals.
According to the Commission Implementing Regulation (EU) No 2004/247/EC of 10^th March 2004, simazine is not approved for use in the European Union (EU) as a plant protection agent, following Regulation (EC) No. 1107/2009. But maximum residue levels of 0.01 mg/kg to 0.25 mg/kg are allowed for the presence of simazine in products of plant and animal origin, according to the EU Reg. No 310/2011.

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Simazine CRM may also be used as given below:

• Development and validation of an ultrasonic-assisted dispersive liquid-liquid microextraction (UA-DLLME) method for sample extraction, followed by gas chromatography-mass spectrometry based determination of endocrine-disrupting herbicides in the river and seawater samples
• Determination of triazine pesticide residues in samples of apples, pears, carrots, potatoes, tomatoes, avocado, cucumber, spinach, bananas, and oranges by modified QuEChERS and solid-phase extraction (SPE) procedures, followed by liquid chromatography-photodiode array (LC-DAD) analysis
• Multi-residue analysis of 67 pesticides in olive oil, olives, and avocado samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to evaluate various clean-up sorbents
• Quantitation of 20 pesticides in eel and shrimp samples by a scheduled multiple reaction monitoring (sMRM) method and QuEChERS with EDTA for sample extraction and purification
• Analysis of 35 micropollutants including pesticides in water samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS) after their solid-phase extraction
• Simultaneous quantification of 58 pharmaceuticals and personal care products (PPCPs) and pesticides in water samples by solvent-based de-emulsification dispersive liquid-liquid microextraction (SD-DLLME) combined with liquid chromatography-tandem mass spectrometry (LCMS/MS)
