473-72-3 Usage
Description
Pinonic Acid is a low-volatility organic compound that forms in the atmosphere as a result of reactions between α-pinene and various atmospheric radicals, such as ozone, OH radical, or NO3 radical. It is known for its unique properties and potential applications in various industries.
Uses
Used in Atmospheric Chemistry Research:
Pinonic Acid is used as a marker for atmospheric chemistry research, particularly in studying the formation and behavior of secondary organic aerosols (SOAs). Its low volatility allows it to contribute to the growth and lifetime of SOAs, which play a crucial role in climate regulation and air quality.
Used in Environmental Monitoring:
Pinonic Acid is used as an indicator for environmental monitoring, helping to assess the levels of air pollution and the presence of specific atmospheric radicals. Its detection can provide valuable insights into the chemical processes occurring in the atmosphere and the potential impacts on human health and the environment.
Used in Analytical Chemistry:
Pinonic Acid is used as an analytical standard in the development and calibration of analytical instruments, such as mass spectrometers and gas chromatographs. Its unique chemical properties make it a valuable reference compound for accurately measuring and identifying other atmospheric constituents.
Used in Air Quality Management:
Pinonic Acid is used in air quality management strategies to help develop effective measures for reducing emissions of volatile organic compounds (VOCs), such as α-pinene, which contribute to the formation of SOAs and poor air quality. Understanding the role of Pinonic Acid in atmospheric chemistry can inform the development of policies and technologies aimed at improving air quality and mitigating climate change.
Check Digit Verification of cas no
The CAS Registry Mumber 473-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 473-72:
(5*4)+(4*7)+(3*3)+(2*7)+(1*2)=73
73 % 10 = 3
So 473-72-3 is a valid CAS Registry Number.

Molecular Chirality and Cloud Activation Potentials of Dimeric α-Pinene Oxidation Products

The surface activity of ten atmospherically relevant α-pinene-derived dimers having varying terminal functional groups and backbone stereochemistry is reported. We find ～10% differences in surface activity between diastereomers of the same dimer, demonstrating that surface activity depends upon backbone stereochemistry. Octanol-water (KOW) and octanol-ammonium sulfate partitioning coefficient (KOAS) measurements of our standards align well with the surface activity measurements, with the more surface-active dimers exhibiting increased hydrophobicity. Our findings establish a link between molecular chirality and cloud activation potential of secondary organic aerosol particles. Given the diurnal variations in enantiomeric excess of biogenic emissions, possible contributions of such a link to biosphere:atmosphere feedbacks as well as aerosol particle viscosity and phase separation are discussed.

Abstract: Optically active cyclobutanediyl- and cyclopropanediylbisalkylidenedihydrazides of isonicotinic and salicylic acids were synthesized when theperoxide products of ozonolysis of (–)-α-pinene and(+)-Δ3-carene were reduced with isonicotin
Transformations of (-)-α-pinene peroxide ozonolysis products by hydrazines of HCL and H2SO4

The reactivities of hydrazines of HCl and H2SO4 for (-)-α-pinene peroxide ozonolysis products were studied. It was shown that these reagents were less effective and selective than semicarbazide hydrochloride for transformations into cis-pinonic acid and its esters.
